The Yamaha DTX900M Sound Module combines the sound of the world's best acoustic drums with Yamaha's extensive knowledge of digital sound technology. This module will not only give you the sounds of some of Yamaha's flagship kits, but numerous other kits from throughout history. This module utilizes actual samples of real drums; giving you a true, honest sound that doesn't need to be heavily processed to sound good. By incorporating the Xpanded Articulation technology from the MOTIF series, Yamaha creates subtly different samples even when you strike the drum with the same force. This will deliver more natural snare rolls and accurately recreates the feel of a hi-hat or ride cymbal.

With 512MB of Sampling Memory onboard, the DTX900M allows you to record new sounds and assign them to the pads, or import samples via a USB memory device right out of the box. This lets you stay current with musical trends and take advantage of the many drum libraries available without having a computer on stage. This gives the casual electronic drummer fresh, new tones to play with while giving the more advanced player the ability to further tweak those voices with the DTX900M’s effects settings.

Modern drum production techniques require that the effects have the same attention to detail as the drums themselves. The DTX900M has three DSP effects blocks per kit that can be configured to produce these sought after sounds. The reverb effect has presets from the legendary SPX2000; the chorus features traditional effects as well as tempo-based delays, phasers and flangers; and the variation block can be routed as either a send or insert, to recreate buss-compression -- a studio technique whereby compressed sounds are mixed with the “dry” signal to add punch without squashing the expressiveness of the performance. Add up the individual EQs for each drum and include the master effect and master EQ and you have all the processing needed to create killer sounding drum tracks live or in the studio.The DTX900M includes some extra features that any drummer can appreciate. For example, the 50 preset kits and 50 user kits allow you to find the perfect sound for the gig. In addition, you can use a USB memory device to hold 1,584 additional user kits for instant recall. The popular Groove Check feature has been expanded to display the timing of up to 5 individual triggers at once. There is also a USB “to host” connectivity that allows you to easily connect to a computer using a single USB cable.

what an amazing product!. ive used every drum kit from the td4 to the td30, let me tell you this mod can hang with any drum set acoustically or electronically any where, time or place.the sounds that this product produces are simply astonishing. it gives a accurate touch response giving you the ability to use your true feel.its great if you have neighbors because unlike a acoustic drum kit you can use head phones, you can create your own drum kit with the many user pre sets.i had it rigged with a dtx 400 and it sounded just as good as anything else(yes you can do that).it comes with 512mb of memory but you can upgrade if you need to.i am a reviewer at SAM ash las vegas, jason l
